1. What is the chemical principle of anti-corrosion coating anti-corrosionThe chemical principle of anti-corrosion is to neutralize harmful acid and alkali substances into neutral harmless substances to protect the materials in the anti-corrosion coating from the erosion of corrosive substances.
2. Corrosion prevention is to achieve the purpose of extending the service life of metal items that are prone to corrosion by taking various means (methods) to protect them. Physical anti-corrosion, chemical anti-corrosion, electrochemical anti-corrosion and other methods are usually used. Usually, the metal surface will be accompanied by dust, oil, oxide skin, rust layer, pollutants, salt or loose old paint film.
3. What is the anti-corrosion principle of anti-corrosion coating? The coating film of anti-corrosion coating prevents the corrosive medium from contacting the surface of the coated object through shielding, thus playing an anti-corrosion effect. It separates the passage of the corrosion battery and increases the resistance. For example, epoxy glass scale anti-corrosion coating is this shielding type. Industrial anti-corrosion paint.
4. The principle of micro-battery is that when it contains a large amount of metal zinc powder in the anti-corrosion coating, it forms a micro-battery composed of zinc powder and substrate steel plate. Electrochemically, zinc is a more active metal than steel, so the current flows from zinc to steel, the zinc-containing coating becomes the anode, and the steel becomes the cathode, so that It protects steel from corrosion.
Color paint layer, as the name implies, is a colored paint layer, giving the most intuitive color feeling. The varnish layer, the outermost layer of car paint, is mainly used to improve the gloss of the paint, improve the texture, prevent ultraviolet rays, and prevent slight scratches.
They are electrophoretic layer, middle coating, color paint layer and varnish layer respectively. ElectrophoresisLayer: The electrophoretic layer can be roughly regarded as a paint layer directly attached to the body steel plate, so it is also called primer. Intermediate coating: The intermediate coating is a layer of paint between the electrophoretic layer and the color paint layer, and the intermediate coating is sprayed by robots.
varnish layer The varnish layer is the outermost layer of car paint, a transparent paint layer that we can touch directly with our fingertips. The function of varnish is mainly to improve the gloss of the paint, improve the texture, prevent ultraviolet rays, and prevent slight scratches.
They are electrophoretic layer, middle coating, color paint layer and varnish layer. The electrophoretic layer is used to prevent rust and improve the binding force of the paint layer. The intermediate coating plays the role of connecting the colored paint layer and the electrophoretic layer. The varnish layer is the outermost layer of the car paint. The main function is to improve the gloss of the paint, enhance the texture, prevent ultraviolet rays and slight scratches.
So, the paint surface is not a simple single layer like furniture paint, but is usually composed of phosphate film, electrophoretic layer, medium paint, color paint layer and varnish layer, etc. Among them, the phosphate film and the electrophoretic layer should be the primer, and the color paint layer and the varnish layer should be the topcoat. Metallic paint: also known as metallic glitter paint, it is a popular car paint at this stage.
Car paint consists of three parts: primer, intermediate coating and topcoat. Since car beauty and maintenance are mainly for topcoat, we focus on the ingredients and characteristics of car topcoat. Automobile surface paint is divided into two categories, namely original color paint (commonly known as plain paint) and metallic glitter paint (commonly known as metallic paint), accounting for roughly half of each.
1. You can imagine. The life of the car is greatly reduced, so it is necessary to paint the car. The coating can protect the car from corrosion. With the launch of new materials, coatings play an increasingly important role, such as high scratch resistance, elasticity, anti-pollution, etc.
2. Automobile coating belongs to advanced protective coating. The resulting coating must have excellent corrosion resistance, weather resistance, acid resistance and alkali resistance, and erosion resistance to debris, etc., and have a wide range of adaptability.
3. Protection effect: Most of the materials made of automobiles are steel materials. If there is no protection of paint coating, it is inevitable that the surface will rust in the process of long-term wind and rain, resulting in a sharp reduction in the service life of the car.
4. Protective effect: Cars are often eroded by moisture microorganisms, ultraviolet rays and other acid and alkali gases, liquids, etc., and sometimes they are worn and scraped to cause damage. If it is painted on its surface, it can protect the car from damage and extend its service life.
5. Protection effect: protect metal, wood, stone, plastic and other objects from the erosion of various media such as light, rain, dew and hydration. Using paint to cover objects is one of the most convenient and reliable protection methods, which can protect objects and extend their service life.
There are three types of automotive paint, namely ordinary paint, metallic paint and pearl paint. Automotive paint is the outermost layer of car paint. Generally, it is required that the surface paint needs to have more complete performance than the underlying paint, and it is also a decisive existence to add color to the appearance of the car.
There are ordinary paint, metallic paint and pearlescent paint. Next, let's briefly introduce the car paint to our friends! Automotive paint: PPG water-based paint Maserati uses PPG water-based paint, and there are quite a lot of painting processes, which affects the complexity of the post-maintenance process. This is the news mentioned above that Maserati transported car paint craftsmen from Italy by air.
6 car repair paint.According to the coating method, it is classified: 1 electrophoretic paint for automobiles; 2 liquid spray paint for automobiles; 3 powder coatings for automobiles; 4 special paints for automobiles, such as polyvinyl chloride sealing paints; 5 post-coating materials.
The supporting product line of automotive repair paint includes masterbatch, varnish, curing agent, diluent, 2K medium primer, IK Su Ash (gray primer), plastic primer, atomic ash, eye filler, ripplease, degreaser, IK blending resin, etc. There are usually the following specific performance requirements.
The classification of automotive paint mainly includes three types: ordinary paint, metal paint and pearlescent paint. Ordinary paint is the simplest, low cost, low hardness, and is mostly used in trucks and buses.
There are generally four basic components of automotive paint: film-forming materials (resin), pigments (including physical pigments), solvents and additives.Film-forming materials are the main components of coatings. Its function is to keep the pigment bright, firm and durable, and able to adhere to the surface of the object. It is the material that determines the type of paint.
The middle coating of the car can be firmly attached to the surface of the primer, and it can also be easily combined with the topcoat on it to play a connecting role. It has good moisture-proof and polishing performance, which can close the small defects at the bottom and improve the fullness of the paint surface. The middle paint is the paint used between the car primer and the topcoat or primer.
Automotive explosion-proof coating is a special coating applied to the surface of automobile glass to provide additional safety and protection. This coating is usually composed of multi-layer films, including polymer materials, ceramic particles or other reinforced materials.The main function of the explosion-proof coating of automobiles is to reduce the damage of broken glass splashes and debris.
The coating can be gas, liquid or solid. The type and state of the coating usually depend on the substrate to be sprayed. Automotive paints, including body paints, are generally composed of three layers of primer, middle coat and topcoat or primer and topcoat. Depending on the type of paint used, the name is also different.
